13 Claims.

The present invention is directed to an im-- proved device forextracting juices out of compressible foods and specifically isconcernedwith a fruit juice extractor having a linearly movable pressure applyingmember adapted to be displaced towards or away from a suitable foodsustaining anvil mounted in a juice collecting and draining receptacle.Juice extracting devices of the type alluded to are generally providedwith a rotatable control lever for actuating a shaft carrying a pinionwhich is in mesh with a toothed rack sustaining the pressure applyingmember. Obviously where the lever is relatively long, less force isrequired during squeezing operations in that the mechanical advantagehas been increased. With such increased mechanical advantage it has beendiscovered that usually the supporting base for the extracting device isinadequate and unless firmly anchored, there is danger of accidentaltilting of the extracting device. Consequently a portable juiceextracting device with a relatively longer operating control leverrequires an enlarged supporting base to prevent tilting or undesirabletipping of the extracting device but an enlarged supporting baserequires more space generally and even for storage or transportation.The present invention has as its primary object to provide a compact andportable juice extracting device wherein the base thereof embodies abalancer or stabilizing means which can be conveniently and quicklyextended to compensate for the increased extension of the control lever.Conversely, the invention has as a further object to provide aserviceable and improved juice extracting device wherein the controllever may be easily extended or reduced in length to compensate for theextent of the projection of the stabilizing means or balancer slidablysustained by the base. Another object of the invention resides in theprovision of a supporting base having means for rectilinearly guiding abalancing member movable towards or away from an upstanding andrearwardly. disposed column for stabilizing the base against tilting. Afurther object is to provide a yoke for slidably guiding a basebalancing member which is adapted to be withdrawn from the base orretracted therein. Another object is realized in providing stop means tolimit the withdrawal of the balancing member from the base or theretraction thereof into the base. Another object is to provide aserviceable fruit juice extractor which may be easily operated withoutheavy exertion on the part of the operator and which when not in useoccupies a relatively small space even 2 though embodying means tostabilize the base and means for enlarging or reducing the mechanicaladvantage of the control lever. Other important objects and functionaland structural features of the invention will appear from the followingdetailed drawings taken in connection with the accompanying drawingswherein:

Fig. 1 is a side view of the fruit juice extractor according to myinvention, illustrating in full lines the slidable balancer retractedinto the base and in dash and dot lines the balancer is extended orwithdrawn from the base.

Fig. 2 is an underneath or bottom view of Fig. 1.

Fig. 3 is a fragmentary and nlarged sectional view of the control lever.

Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 2.

Fig. 6 is a vertical sectional view on the bent plane 66 of Fig. 5.

Fig. 7 is a fragmentary View of Fig. 5 with the juice collecting anddraining receptacle removed from the column, and

Fig. 8 is a front elevational view of the juice collecting and drainingreceptacle.

The fruit juice extracting device or extractor is generally designated Ehaving the base B appropriately carrying the standard or column Cembodying the vertically arranged opening In for slidably guiding thetoothed rack H fixedly carrying the hood or pressure applying member Pprovided with the depending annular flange l3 removably receivable inthe annular juice collecting and draining dish or receptacle I4removably and appropriately mounted on the shelf or arouate flange Sextending forwardly from the column C. v

Thev column C has a boss 20 sustaining the rotatable shaft 2| to whichis fixed the pinion 22 in mesh with the rack II. The shaft extends intoa bushing 23 and an adjustable set screw shaft. The bushing 23'is a partof the operat- If the lever be'rotated-to shift hood-P -towards I theanvil l5, fruit mounted on the latter will be contacted by the arcuatepressure applying sur--- face A which moves towards the anvil-andthe;

Where the operating lever .is. in its leastextended position illustratedin Fig. 1,, the base atvv times-may be inadequate to preventtiltingpfithe extracting device where a relatively-large force.

that is, its rear. end. tilts upwardly, pivoting on the .forwardendofthe, base. Under such.,cir-

cumstances, danger of, undesirably tipping the,

By thepresent. invention if-the ,leverbe exec tended, that is, :byprojecting, the handle, a-rela s tively light force is required forcompletelyv squeezing the fruit. Withithe handle-extended,

tends beyond the base B even if the balancer is fully retracted and aslight finger thrust applied to Wing or terminal 52 will withdraw orproject the balancer forwardl of the base. The lip or arm 49 althoughintegral with bar 56 extends below the latter and has its bottom surfaceflush with the bottoms of the supporting feet 56 fastened to the base Band the column of the extracting device.

In' operation, the fruit on the-aanvil iscrushed by the pressureapplying-member Pon rotation of the control lever. Where certainresistance is offered by the fruit or where the operator desires to,-apply-a, -lighter force, the lever may be quickly extended bywithdrawing the handle. There after-the balancer 48 may be quickly setto a withdrawn portion, in front of the base by actuating themanipulator or lip 49.
